RX2540 M5 Operating Manual 21
Power supply unit (PSU)
The server can be equipped with:
– with up to two AC PSUs
In its basic configuration the server has one PSU that adjusts automatically
to any mains voltage in the range of 100 V - 240 V (AC PSU Platinum) or
200 V - 240 V (AC PSU Titanium). Besides the PSU, a second PSU can be
installed optionally to serve as a redundant power supply. If one PSU fails,
the second PSU in the redundant configuration ensures operation can
continue uninterrupted and the defective PSU can be replaced during
operation (hot-plug). The second PSU can be installed during operation.
– with up to two DC PSUs
In its basic configuration the server has one PSU that adjusts automatically
to any mains voltage in the range of -40.5 V - -57 V (DC PSU -48 V) or 200
V - 380 V (HVDC PSU 380 V). Besides the PSU, a second PSU can be
installed optionally to serve as a redundant power supply. If one PSU fails,
the second PSU in the redundant configuration ensures operation can
continue uninterrupted and the defective PSU can be replaced during
operation (hot-plug). The second PSU can be installed during operation.
– with one AC PSU or DC PSU and one PSU dummy cover
Advanced Thermal Design (ATD)
The ATD option allows you to operate the system with a wider temperature
range either of 5 °C to 40 °C or 5 °C to 45 °C, depending on your system and
configuration.
V CAUTION
In a system that is configured with ATD, only certain components which
support the respectively increased higher operating temperature range
may be installed and used. For applicable restrictions, see the official
configurator tool.
This option can only be ordered from the
manufacturer and is indicated by the respective
logo on the identification rating plate.
